Applying Taguchi to Load Development

By Joe Berk

People reload ammunition for different reasons. It used to be you could save money by reloading, and I suppose for the more exotic cartridges (any Weatherby ammo, the big elephant rounds like .458 Win Mag, the .416 Rigby, etc.) that’s still the case. It’s not the case for the more common rounds like 9mm, .45 ACP, and .223 Remington; bulk ammo for those is so inexpensive you’d be hard pressed to reload for as little as that ammo costs. Sometimes people reload because factory ammo is no longer available or it’s very tough to find. But most of us reload for accuracy. We can experiment with different combinations of components and tailor a combo to a particular firearm to find the sweet spot…that combination of components that provides the tightest groups. I’m in that category; it’s why I reload.

When I’m testing for accuracy and I get a tight group, I always wonder: Is it because of the combination of components, or is it just a random event? Usually, if the group size is repeatable, we conclude that it is the component combination, and not just a random good group that results from all the planets coming into alignment. But is there a better way? You know, one that shows with more certainty that it’s the component combination, and not just a fluke?

This article is a bit different. It’s not just a story about a gun or about reloading ammunition. It includes those things, but it’s more. This story is about applying the Taguchi design of experiments technique to .45 ACP load development for ammo to be used in a Smith and Wesson Model 25 revolver (the one you see in the photo above).

I’m guessing you probably never heard of Taguchi. That’s okay; most folks have not. Taguchi testing is a statistical design of experiments approach that allows evaluating the impact of several variables simultaneously while minimizing sample size. The technique is often used in engineering development activities, and I used it regularly when I was in the aerospace world. The technique was pioneered by Genichi Taguchi in Japan after World War II, and made its way to the US in the mid-1980s. I used the Taguchi technique when I ran engineering and manufacturing groups in Aerojet Ordnance (a munitions developer and manufacturer) and Sargent Fletcher Company (a fuel tank and aerial refueling company).

Taguchi testing is a powerful technique because it allows identifying which variables are significant and which are not. Engineers are interested in both. It lets you know which variables you need to control tightly during production (that is, which tolerances have to be tight), and it identifies the others that are not so critical. Both are good things to know. If we know which variables are significant and where they need to be, we can change nominal values, tighten tolerances, and maybe do other things to achieve a desired output. If we know which variables are not significant, it means they require less control. We can loosen tolerances on these variables, and most of the time, that means costs go down.

Like I said above, I used Taguchi testing in an engineering and manufacturing environment with great success. The Taguchi approach did great things for us. When I worked in the cluster bomb business, it allowed us to get the reliability of our munitions close to 100%. When I worked in a company that designed and manufactured aerial refueling equipment (think the refueling scene in the movie, Top Gun), it helped us to identify and control factors influencing filament-wound F-18 drop tanks. In that same company, it helped us fix a 20-year-old reliability problem on a guillotine system designed to cut and clamp aerial refueling hoses if failures elsewhere in the refueling system prevented rewinding the hose. You don’t want to land in an airplane trailing a hose filled with JP4 jet fuel. Good stuff, Taguchi testing is.

As you know from reading our other Tales of the Gun stories, the idea in reloading is to find the secret sauce…the perfect recipe of bullet weight, propellant, brass case manufacturer, and more, to find the best accuracy for a given firearm. Hey, I thought…I could apply the Taguchi technique to this challenge.

When you do a Taguchi experiment, you need to define a quantifiable output variable, and you need to identify the factors that might influence it. The output variable here is obvious: It’s group size on the target. The input variables are obvious, too. They would include propellant type, propellant charge, primer type, bullet weight, brass type, bullet seating depth, and bullet crimp. We’re trying to find which of these factors provides the best accuracy. I wanted to turn my Model 25 Smith and Wesson into a hand-held tack driver.

The Model 25 is an N-frame Smith and Wesson revolver chambered for the .45 ACP pistol cartridge. It is a superbly accurate handgun, as attested to by the target above.

When Taguchi developed his testing approach, he made it simple for his followers. One of the things he did was define a simple test matrix, which he called an L8 orthogonal array. It sounds complicated, but it’s not. It just means you can evaluate up to seven different input variables with each at two different levels. That’s a bit complicated, but understanding it is a little easier if you see an example. Here’s what the standard Taguchi L8 orthogonal array (along with the results) looked like for my Model 25 load development testing:

As the above table shows, three sets of data were collected. I tested each load configuration three times (Groups A, B, and C), and I measured the group size of each 3-shot group. Those group sizes became the output variables.

The next step involved taking the above data and doing a standard Taguchi ANOVA (that’s an acronym for analysis of variance). ANOVA is the statistical method used for evaluating the output data (in our case, the group sizes) to assess which of the above input variables most influenced accuracy. That’s a complex set of calcs greatly simplified by using Excel. The idea here is to find the factor with the largest ANOVA result. You see, any time you measure a set of results, there’s going to be variation in the results. Where it gets complicated is the variation can be due to randomness (the variation in the results that would occur if you left all of the inputs the same). Or, the variation can be due to something we changed. We want to know if the differences are due to something we did (like changing or adjusting a component) or if they are due to randomness alone. I cranked through the ANOVA calcs with Excel, and here’s what I obtained…

The above results suggest that crimping (squeezing the bullet by slightly deforming the case mouth inward) has the greatest effect on accuracy (it had the largest ANOVA calculated result). The results suggest that cartridges with no crimp are more accurate than rounds with the bullet crimped. But it’s a suggestion only; it doesn’t mean it’s true. The next step is to evaluate if the differences are statistically significant, and doing that requires the next step in the ANOVA process. This gets really complicated (hey, I’m an engineer), but the bottom line is that we’re going to calculate a number called the f-ratio, and then compare our calculated f-ratio to a reference f-ratio. If the calculated f-ratio (the one based on the test results above) exceeds the reference f-ratio, it means that crimping versus no crimping makes a statistically significant difference in accuracy. If it not not exceed the reference f-ratio, it means the difference is due to randomness. Using Excel’s data analysis feature (the f-test for two samples, for you engineers out there) on the crimp-vs-no-crimp results shows the following:

Since the calculated f-ratio (3.817) does not exceed the critical f-ratio (5.391), I could not conclude that the findings are statistically significant. What that means is that the difference in accuracy for the crimped versus uncrimped rounds is due to randomness alone.

Whew! So what does all the above mean?

All right, here we go. This particular revolver shot all of the loads extremely well. Many of the groups (all fired at a range of 50 feet) were well under an inch. Operator error (i.e., inaccuracies resulting from my unsteadiness) overpowered any of the factors evaluated in this experiment. In other words, my unsteadiness was making a far bigger difference than any change in the reloading recipe.

Although the test shows that accuracy results were not significantly different, this is good information to know. What it means is that all of the test loads (the different reloading recipes) are reasonably accurate. If I had used a machine rest, I might have seen a statistically significant difference. Stated differently, the test told me that I needed to use a machine rest with this gun to see which load parameters were really playing a role in accuracy. Without it, my flaky shooting skills (or as the statisticians like to say, my randomness) overpowered any accuracy gains to be realized by playing with component factors.

That said, though, I like that 4.2 grains of Bullseye load with the 200 grain semi-wadcutter bullet, and it’s what I load for my Model 25. But I now know…the gun shoots any of these loads well, and crimping versus no crimping doesn’t really make a difference.

The Warning

Check out these two men and what they did almost a century ago…folks, you couldn’t make a movie this exciting!

The monument above (The Warning, sculpted by Eric Richards) was erected in 2003 in Santa Paula, California, to mark a heroic evening in 1928. Motor Officers Thornton Edwards (on the Indian) and Stanley Baker (on the Harley) were on duty the evening of March 12, 1928, when California experienced the second worst disaster in the state’s history. The recently completed St. Francis Dam, 36 miles upstream in Santa Clarita, collapsed shortly after midnight.

The collapse released 52 billion gallons of water, and that water was headed directly toward Santa Paula. The Santa Paula Police Department learned of the impending danger shortly after the dam broke. Thornton and Baker spent the next 3 hours riding their motorcycles throughout Santa Paula, notifying residents and evacuating the town. Thornton worked for the State Highway Department, which later became the California Highway Patrol. Baker was a Santa Paula Police Department Officer. Although the records from this era are sketchy, legend holds that Thornton’s bike had to be repaired during his midnight ride when it ingested water. As a result of these two officers’ actions, the residents of Santa Paula were successfully evacuated, and few Santa Paula residents died that night.

The water released by the dam (the reservoir had just filled, and the poorly-designed dam was not strong enough to contain it) mixed with mud and debris to form a wall of slurry that advanced 54 miles to the ocean at about 12 miles per hour. The disaster killed an estimated 470 people, and to this day, it is the second worst disaster in California history. Only the San Francisco earthquake resulted in more death.

The Warning contains no mention of either motor officer’s name; rather, it is intended to honor all acts of heroism, and to honor those killed during the St. Francis Dam collapse. If you head through downtown Santa Paula, The Warning is hard to miss. It’s worth a trip to Santa Paula just to see it.

Special thanks for the above research to Peggy Kelly, a reporter for the Santa Paula Times, whom I interviewed for the above information.

Auto Email Updates Are Back!

BajaBound, Arjiu and Dajiu are. Stay tuned! This photo is from a 2008 trip with good buddy Joseph Lee, looking out over Bahia Concepcion. I bought the ’06 Triumph Tiger you see above from Douglas Motorcycles, and it was a grand machine for touring Baja.

It’s been a challenging time, but the WordPress automatic email blog notifications are back on line. I’d like to be able to tell you why the “improvement” caused things to stop working, but I can’t. The people who create the software for this feature (they call it a widget, which is probably and insult to widgets worldwide) advised deleting the update and rolling back to the original version, but that didn’t work initially, either. So we waited a few days (especially after seeing the help board explode with other bloggers complaining about the failure), tried the rollback to the unimproved version again, and voilà, it worked.

Our apologies for the screwup. Eh, these things happen. If you want to sign up for blog update notifications (and we think you should), the widget is in the upper right corner of this page if you’re viewing the ExNotes blog on a laptop, and it’s at the end of this blog on a mobile phone. You might want sign up for two reasons…one, the blog is great, and two, we’re giving away another moto adventure book at the end of this month to one of the folks who get our automatic updates.

Stay tuned, mi amigos, because there’s more good stuff coming your way real soon. Uncle Joe and I are headed into Mexico next week, and you sure don’t want to miss any of the Baja updates!

Morgans and Mr. H…

A 1953 Morgan. This is a dream car for me.

I read the Wall Street Journal pretty much every day. The reporting is far more objective than what passes for journalism in the other papers I take (the LA Times and the NY Times), the stories tend to be better, and there’s A.J. Baime. Mr. Baime is an award-winning historian and a fantastic writer. He does a regular column in the WSJ about interesting people who own interesting automobiles, and the most recent one was about a fellow who fell in love with, and later bought, a Morgan.

A Morgan. Wow, that brought back memories.

Pete Herrington in 1963, when I was in the 7th grade. I was surprised at how easy it was to find this photograph on the Internet.

When I was 12 years old and in the 7th grade, our science teacher (Peter Herrington) owned a Morgan. It was 1953 Morgan, to be specific, and it was unrestored and magnificently original. I was just getting interested in cars and motorcycles back then, and that Morgan was riveting. It was one of the most interesting things I’d ever seen. I couldn’t quite figure it out, but I knew I liked it. In an age when everything was trying to look like a fighter jet, Mr. Herrington’s Morgan was a combination of an old car, a sports car, and attitude. It had sweeping fenders (like an old Model A Ford), it was low slung and a two-seater (like a Corvette), and it had huge louvers and a big leather belt to hold the hood down. Its appearance said I don’t care what I look like, I’m tough, and I’m built to perform. It was cool. To a 12-year-old kid like me, it was beyond cool.

To dive a bit deeper into this story, I was a bit of a problem, you see, when I was 12 years old. Actually, I was a pain in the ass, and I got detention a lot. You might say I was a confirmed detention recidivist, and as such, I spent more time in detention than any other class I had in those days.

Normally, detention would be a bad thing, but our principal rotated detention duty and one day Mr. Herrington drew the short straw. I guess it was inevitable that Peter Herrington would be the detention duty warden one day when I had detention, and this day was that day. The upshot of all this was that I lived about a mile and a half from school, and after cleaning blackboards and doing the other kinds of things kids in 7th grade had to do in detention, I started to walk home when my detention ended. Mr. Herrington was in the parking lot, he fired up the Morgan, and he offered me a ride home. In his Morgan. The one I described above. A ride. In the Morgan. This was punishment?

Now, I won’t tell you that I tried to time my recidivism to coincide with Mr. Herrington’s detention duty, but I will tell you that was not the last time I ever got a ride home after detention in the ’53 Morgan. That car was just so cool. It was a convertible, the door waistline was incredibly low, and it looked and felt like you sat above the pavement at a distance more appropriate for a valve gap than an automobile’s ground clearance. The effect was intoxicating.

Many years later (50 years later, to be specific), I received an email from good buddy Chief Mike (who lives in New Jersey, where I sort of grew up) with an interesting message. Whaddaya know? Mike had bumped into Mr. Herrington at a local mall. It seems our former 7th grade science teacher (still a gearhead and now long retired) had shoehorned an LS-2 Chevy Corvette engine into his Mazda RX-7. He had some questions about the care and maintenance of Corvette motors, and everyone in New Jersey knows Mike is the guy to see if you have a Corvette question.

As Mike was telling this story, a lot of memories flooded back. All of us have had great teachers, and Mr. Herrington was mine. Like I said above, I was a first-class pain-in-the-you-know-what in junior high school (and in high school, too, for that matter), but my 7th grade science class held my interest. Science was cool and so was my teacher. It’s probably why I became an engineer.

To make a long story a little less long, I Googled Mr. Herrington’s name. Yep, there he was. There’s his address. A quick 411 call and a few minutes later I had Mr. Herrington on the phone. How about that? Fifty years since I’ve seen this guy, and now I’ve got him on the phone.

You know, a voice is a funny thing. Mr. Herrington, then well into his 80s, sounded exactly as I remembered him. Strong, firm, and focused on gearhead stuff. He told me that the RX-7 was a good car, but the original rotary piston engines were only good for about 75,000 miles (he’d been through several of them, he said). Dropping a Corvette engine into an RX-7 was the way to go, and that’s what he had done. He spoke about it like it was changing tires (a classic Peter Herrington trait).

We had a great conversation. He told me he remembered me, which I kind of doubted until he asked me a question about my father. “Your Dad was the guy who designed and built his own swimming pool, including the filtration system, right? He made the filter tank out of an old wine vat?” That was so long ago I had forgotten about it, but not Mr. Herrington. Wow!

I told Mr. Herrington I felt bad about being such a bad kid and such a royal pain in the ass back in the 7th grade, and he said, “Ah, don’t worry about it. That’s what you’re supposed to do when you’re that age…” Just like that, years of guilt evaporated. It was a good feeling.

I sent Mr. Herrington a signed copy of 5000 Miles at 8000 RPM and we had a couple of great conversations after that touching on cars, motorcycles, careers, health, life, and other topics. And then one day his wife wrote to tell me he had passed away. That was a tough email to read, but I felt incredibly fortunate to have reconnected with Mr. Herrington, and I think he enjoyed it, too. A.J. Baime’s article in the Wall Street Journal made me think about him again. Thank you, A.J. Baime, and thank you, Peter Herrington.

A Savagely-inexpensive rifle…

My new-to-me Savage 340 in .222. It’s got a scope and the whole shebang set me back $180. Such a deal!

I’m a rifle enthusiast, I can’t pass on an interesting experience, and I’m cheap. So when I was in a local gunshop a year or so ago, I was surprised and intrigued to see a consignment rifle go on the rack at a ridiculously low price. It was a 50-year-old Savage 340 bolt action rifle in .222 Remington (complete with a period-correct 3×9 telescopic sight) for only $180.

A Bushnell 3×9 scope was included with the deal!

This is a rifle that probably sold new for around $35 or $40, but like I said, that was 50 years ago. These days, any kind of a shooter for $180 is a steal. I was immediately attracted to the Savage by the price and the thought that it might make for a nice gunstock refinishing project. What really got my attention, though, was the cartridge for which it was chambered: The .222 Remington.

I’ve never owned a gun chambered in .222 Remington. The Triple Deuce is a cartridge that has a cult following because it is one of those special numbers known to be inherently accurate. It’s very similar to the .223 Remington (the 5.56 NATO round), but the .222 is a little bit shorter with a longer case neck. It’s proportions are said to be ideal for phenomenal accuracy. Like I said, I’ve never had a .222, but for $180, I could afford to find out if the stories were true.

Okay, on to Step 2 of this saga, and that’s the reloading aspect. Accuracy can be greatly enhanced by reloading. You know, that’s the deal where you save the fired brass, resize it in a reloading press, punch out the old primer, insert a new primer, load a precisely-controlled amount of new gunpowder, and seat a new bullet. Oilà…you have a reloaded round ready for firing. The deal with reloading is that you can experiment with different powders, different powder weights, different primers, different brass manufacturers, different bullet makers, different bullet weights, different bullet seating depths, and more. The concept is that you can tune the ammunition to precisely match a rifle’s preferences and achieve improved accuracy. I’ve been reloading ammo for close to 50 years and I’m here to tell you it works.

Now, back to that Savage rifle. I waited my obligatory 10 days (the Peoples Republik of Kalifornia’s “kooling off” period) and in Governor Gavin’s eyes I guess had cooled off sufficiently. I picked up my new-to-me, 50-year-old Savage and loaded several different combos to see how the old 340 would work. In a word, it was awesome…

Impressive results for the first time out with a 50-year-old rifle. These groups were fired at 50 yards; the next steps will involve experimenting around the best load and testing for accuracy at 100 yards. The recipe for the tiniest loads was a 55-grain Hornady full metal jacket boat tail bullet, a cartridge overall length of 2.176 inches, and 22.6 grains of IMR 4064 propellant.

You can see that different loads do indeed result in different accuracy levels. This is encouraging stuff, and what makes it even more promising is it shows the results of just one reloading session. The load that printed a 0.538-inch group is clearly pointing toward what the Savage likes, and my next set of loads will refine that combination. Good stuff and great fun, and all with a rifle that only cost $180!

Tractor Supply

It seems like I’m always working a pick and a shovel at Tinfiny Ranch. Situated at 6000 feet in the foothills of the Sacramento Mountains the place is steep with many elevation changes. An arroyo runs past the house so that when it rains (and it rains a lot in New Mexico) my driveway becomes a short-lived trout stream.

Water, being the universal solvent, plays havoc with Tinfiny Ranch and most of my time is spent trying to bend it to my will. Armed with hand tools and 50-pound bags of concrete I’ve managed to carve out a dry spot to sleep. The landforms here are fleeting, changing and slowly make their way 1500 feet down to the Tularosa Valley where huge dust storms blow the accumulated material back up onto the mountain sides. You don’t own real estate here: you trap it.

When Hunter called me to tell me he had found a Kubota tractor for me my first thoughts were about water. Like a slightly soft football a front loader tractor would give me a leg up on erosion. I was on my way to Stillwater a few days later.

Hunter is my riding buddy. We both like crappy old two-strokes and we’ve run them clear across country following the Trans-America Trail. We’ve passed some impassable routes and had bikes lay down on us in the middle of the desert. I know him as Vinnie The Snake from the dirt and only the dirt but it turns out there’s more to Hunter than a beat up old DT400 Yamaha.

We had a day to kill before I picked up the tractor so we went to Hunter’s Skybox at OSU and watched the OSU women’s basketball team dismantle a team from Kansas. The governor of Oklahoma has a suite two doors down and there was unlimited free food along with all the ice cream you could eat. The suite had a commanding view of both the football field and the indoor arena.

When we walked in the coach shook Hunter’s hand and then he shook my hand like I might also be somebody important. Then the TV and radio guys chatted up Hunter including me in the conversation. It was weird: nobody ever cares about what I have to say but my proximity to Hunter earned a listen. Everyone knew and loved Hunter and they loved me too. Nobody called him The Snake. It’s like there are two Hunters, one that lives in a world unlike any I’ve seen. I’ll remember that other, respectable Hunter when he’s tipped over in a mud hole cussing his two stroke.

The Tractor was a beauty with tires so new they still had rubber bar codes visible. Kubota’s have earned a good name in the heavy equipment arena and this L2850 sported a diesel engine that fired right up.

Underneath the driven front end you’ll find a portal-type axle to give the tractor plenty of ground clearance. Everything is leaking a bit but oil is cheap and Tinfiny can use a little dust control. The steering felt tight and Woody, the guy I bought the tractor from takes good care of his stuff.

When I worked construction in Miami it was rare to see a dashboard unbroken. Vandalism was a constant problem. Lights, tires and hoses were routinely damaged by bored kids. The L580 dash was clean and everything works except the tach needle fell off.

At the rear of the Kubota has a two-speed PTO drive that I will be using as soon as CT buys me a backhoe attachment. Amazon has some cool 3-point hoes costing around $3600. You don’t want to do a lot of side digging with a 3-point hoe because the hitch wasn’t meant for big side loads but as long as you are crabbing in a straight line they will work well.

The transmission has high and low range with low range, first gear being super slow. Top end of the tractor in high range-high gear is around 12 miles per hour. With zero suspension 12 MPH is plenty over Tinfiny’s rough grounds.

This lever engages the front wheels. This is pretty important because the front end loader combined with nothing attached to the hitch means the big rear wheels have little traction.

The Kubota’s grille was bent a bit but Woody had a new grille that he hadn’t gotten around to installing. The rest of the tractor is pretty straight. The side lights need new lenses and the back lights could use some love but all in all I’m thrilled with the tractor. How could I not be? Every boy loves a tractor.

The Ruta del Vino

This post will wrap up our Tecate visit, and the focus of today’s blog is the road south out of Tecate. The Ruta del Vino is a magnificent road that runs through the northern Baja countryside to Ensenada, passing directly through one of Baja’s wine growing regions.

If you missed the earlier Tecate posts, here are the links:

Tecate
Malinalli Sabores Autóctonos!
A Tecate Sunrise

Getting to the Ruta del Vino is easy. After entering Baja through Tecate, just continue south. You’ll pass under the Tecate sign shown in yesterday’s blog, hang a left on Avenida Revolución, and then turn right on Boulevard Universidad (which becomes the Ruta del Vino and Mexico Highway 3).

You’ll pass through the center of Tecate and climb a hill as you leave Tecate. You’ll see a bunch of pottery stories selling clay bowls of all kinds. A little further south is a monastery on your left, and a little beyond that is a sign over the road welcoming you to the Ruta del Vino.

The Ruta del Vino has several things to offer. The first is magnificent scenery through Mexican countryside. Then there are the vineyards. They are on both sides of the road. The third are the restaurants and hotels. And I guess the fourth is the destination, as the Ruta del Vino runs all the way to El Sauzal, a tiny community on Ensenada’s northern edge. That’s where the Ruta del Vino intersects with Baja’s Transpeninsular Highway. Turn left and the Transpeninsular Highway will take you through Ensenada and all the way to Cabo San Lucas. Turn north and you’re on your way to Tijuana and San Diego.

Along the Ruta del Vino, which is Mexico’s Highway 3.

Northern Baja wines are surprisingly good. I’m not a wine connoisseur; I just think they are good and they are certainly reasonably priced. My favorite vineyard is the L.A. Cetto vineyard, which is roughly 45 miles or so south of Tecate. As you’re traveling south on the Ruta del Vino, the L.A. Cetto vineyard is on your left. The road to it used to be dirt, but it was recently paved and it’s an easy ride now. The L.A. Cetto vineyard usually has a fair crowd and on our last visit, there was a general feeling of excitement in anticipation of a visit by senior members of the Catholic clergy. As we were leaving, an entourage of several priests and the region’s Cardinal were arriving.

The now-paved road leading to the L.A. Cetto Vineyard. That’s my Subie Outback, which is a grand automobile for these kinds of tours.

A Mexican motorcyclist on the road to the L.A. Cetto vineyard. All the gear, all the time. The motorcycle is a Zongshen, marketed in Mexico under the Italika name.

The L.A. Cetto grapes. This is a composite photo showing a 180-degree view from the south (on the left) to the north (on the right). It’s stitched together from three photos. Photoshop does a great job at these kinds of things.

The L.A. Cetto vineyard offers wine tasting, and they sell wines, vinegars, olive oil, olives, cheeses, nuts, and more. When I’m on the motorcycle, my friends and I will usually stop to buy some cheese and olives for a snack. The vineyard has outdoor tables in front of the wine tasting areas. The vineyard also offers factory tours, but they were only in Spanish on the day of my most recent visit. You can buy and get back across the border with any amount of olives and olive oil you wish to take, but there’s a one bottle limit on wine. I picked up an L.A. Cetto Malbec on this visit, which I’ll try later this month. If you’d like to read more about the L.A. Cetto vineyard, here’s an excellent article in the BajaBound.com newsletter.

We had a great lunch at Los Naranjos, which is just a short jaunt further south on the Ruta del Vino. It’s about a half mile down the road on the right. The cuisine there is impressive, and nothing wraps up a great meal at Los Naranjos better than their apple pie. Make sure you try a glass of their namesake orange juice, too. They grow their own oranges and squeeze their own juice. It’s superb. One more thing: The salsas at Los Naranjos are the best I’ve ever had. One in particular was a darker salsa with crushed almonds. I asked if I could buy a bottle of it, but Los Naranjos doesn’t sell this one other than as a serving with each meal. They saw how much I liked this particular salsa, though, and the chef made up a couple of plastic containers for me to take home.

Inside Los Naranjos. It’s rare to see it this empty. On Sundays, it’s a favored destination for Mexican riders and it’s packed.

Susie and I split a shrimp omelet for lunch. This was just half of the normal serving.

Los Naranjos is part of a larger country estate. You can walk around the grounds and take in the interesting sculptures, birds, tilework, and more. I also found out that there’s a 30-room hotel on the premises, something I did not know before this trip. I think a stay there will find its way into a future Baja itinerary.

To put all this in perspective, all the recent blog posts about Tecate and the Ruta del Vino described what Susie and I did in less than 24 hours. We rode down from the Los Angeles area in the afternoon on a Thursday, crossed the border into Tecate around 4:00 p.m, had our great dinner at Amores that night, we enjoyed a wonderful breakfast in Malinalli Sabores Autóctonos the next morning, we explored downtown Tecate later that morning, and did our trip along the Ruta del Vino in the afternoon. Then it was back up to the border to get back into the US that afternoon.

Waiting in line to cross the border. The Wall already exists. That’s the US on the other side. It would have been a lot quicker getting through on the motorcycles.

Wall art as we waited to cross the border. Photo by Susie.

Getting back to the border is not too hard to do, and the lines to get back into the US are generally better than they would be in Tijuana. Just follow the Ruta del Vino back into Tecate, and as you near the center of town, watch for the Garita (border) signs. You have to turn off to the right and parallel the US border for a mile or so, and then make a U-turn to get in line. On this last visit, because we were in the Subie, we had to get in the car line, and our wait was about an hour (you’ll want to take a restroom break before you get in line). If you’re on a motorcycle, though, you can get through a lot easier. Just find your way through Tecate to the point where the line of cars approaches the US border crossing, squirt through an opening in the K-barriers, and cut the line. We do this all the time on the bikes.

And folks, that was our whirlwind one-day Tecate junket. I liked this approach where instead of zooming up and down the peninsula, we selected a particular place and explored it in some detail. I’d like to do that in the San Quintin area on a future trip…there are some cool things down there. Anyway, Joe G and I are headed to Baja later this month on the motorcycles. Stay tuned; it’s going to be another grand trip!

Our newest advertiser: The San Francisco Scooter Centre

We’re proud to announce that our newest ExNotes advertiser is the San Francisco Scooter Centre, and I thought I might take a moment to tell you how we came to know Barry Gwin and his fine shop.

Barry Gwin, San Francisco Scooter Centre proprietor and scooter maestro extraordinaire, with his private collection of vintage Lambrettas.

About 10 years ago when I was a consultant to CSC, the company was manufacturing the Mustang scooters. I was one of the guys responsible for talking to potential CSC dealers, and one of the dealers I contacted was the San Francisco Scooter Centre. My research indicated that these guys were the “go to” spot for all things scooter-related and that they were the heart of the scooter scene in San Francisco.

CSC ultimately decided not to sell through dealers (you can read all about that in 5000 Miles At 8000 RPM), but when I spoke to Barry Gwin at the San Francisco Scooter Centre, I was impressed for several reasons. I didn’t know Barry from Adam at the time (and he didn’t know me), but he took my cold call and spent an hour on the phone with me. I learned more in that one hour about how a dealer approaches the question of taking on a new line than I had in all of my time with the other prospective dealers. The other dealers I spoke with were condescending and cynical; Barry was polite, patient, and informative.

A year or two later, Sue and I were watching an episode of American Pickers (one of our favorite TV shows) in which Mike and Frank had purchased a very rare Vespa Ape (it’s pronounced “Op Ay” and it’s a Vespa three-wheeled cargo vehicle). On the show, Mike and Frank took the Ape to an expert to get it appraised, and that expert was none other than Barry Gwin at the San Francisco Scooter Centre. “Hey,” I told Sue, “I know that guy!”

The Holy Land for San Francisco scooteristas…the San Francisco Scooter Centre!

Sue and I are in Nor Cal on a fairly regular basis, and I knew I wanted to get into San Francisco and meet Barry in person some day. Well, that some day was back in May of 2018. I sent Barry a note, he said sure, come on in, and we did. It was a hell of a day.

We drove into the city early in the morning and we got lucky (we found a parking spot directly in front of Barry’s dealership). We entered to find a big guy staging scooters for the day’s service activities. That guy was the world-famous Diego, Barry’s premier scooter tech (if you don’t believe me on that, do a search on Google and see what shows up). I asked if Barry was in, Diego told me Barry would be in a little bit later, and when I asked about finding a good coffee shop nearby, he pointed us in the right direction. The coffee in downtown San Francisco was great, and Sue and I shared a WBE chocolate-covered coconut macaroon (as in “world’s best ever”).

After enjoying our macaroon, we crossed the street to go back to Barry’s shop. We met Barry, and he immediately introduced us to Lunchbox (his 11-week-old bulldog pup). Barry gave us the grand tour…the showroom, the service area, the parts and accessories area, and his private collection of Lambrettas and other vintage scooters upstairs. It was really cool stuff.

Meet Lunchbox when he was a youngster back in May 2018, a very cute and friendly pup!

While Barry was busy helping a new scooter rider select a helmet, Sue and I chatted with a guy named Steve and his wife, Debbie, who had just flown in from England. Debbie told us that she had always wanted to visit San Francisco, but Steve did not want to make the 11-hour flight from London until she told him about the San Francisco Scooter Centre (it seems Steve is a vintage scooter enthusiast, too). That sealed the deal for a trek to America. It was a funny story told with a delightful British accent. Imagine that…flying across an ocean and a continent to see a scooter dealer!

New bikes on the showroom floor…that’s Steve and Debbie on the right, who flew in from England!

New Genuine Buddy scooters. We sold these a few years ago. They’re great scooters.

We spent a lot of time with Barry on the second floor, where he keeps the vintage stuff. It was an amazing collection, and it was obvious Barry loves his bikes and all that goes with finding, restoring, and in some cases, hot rodding vintage machines.

Vintage scooters in Barry’s personal collection. When buying from any dealer, it’s always better if the owner is a rider and an enthusiast. Barry fits that description.

It was a great day for us, and spending it with Barry at the San Francisco Scooter Centre made it even better. This is a guy who knows his stuff, and it’s obvious why Barry’s dealership has become the epicenter of the San Francisco scooter scene. I was impressed before I met Barry; I’m even more so now.

But wait, as they say…there’s more. As a Genuine dealer, Barry also sells the new Genuine G400C motorcycle. That’s an interesting bike to me on many levels. I first saw it when I rode across China a couple of years ago and the bike was intriguing. The one I saw was customized to look like a 1960s Triumph, and I think the Chinese manufacturer (Shineray, pronounced Shin-you-way) out-Triumphed Triumph. To me it was more evocative of the earlier Triumphs I knew as a teenager than are the current Bonneville reproductions, although I’ll tell you I sure like the modern Triumphs (and I’ve been thinking real hard about a new Bonneville).

A Shineray 400 single, with good buddy Lin on board in Qingdao, China.

Another photo of the Shineray in China. It’s a bike that really looks and feels like a Triumph Bonneville. I like the idea and the size makes sense.

So it was that bike you see above that Genuine rebadged and imported with modifications to become their G400C model, and I like the idea of it. I’m going to be in San Francisco in the near future, and if Barry still has any G400C motorcycles in stock I’ll grab some photos and post them here on the ExNotes blog.

The Genuine G400C motorcycle. I like it.

So there you have it. If you’re in San Francisco, drop by Barry’s shop and say hi. Tell him the ExNotes crew sent you and maybe he’ll let you pose for a photo with Lunchbox. The San Francisco Scooter Center is a fascinating place with great people and I think it’s well worth a visit. Tell Barry Joe sent you.

Tecate…

Getting into Mexico through Tecate is about as easy as it gets. All you need to do is find your way to California Highway 94, which twistiliciously parallels the border below Interstate 8 (the mind-numbingly boring slab that runs from San Diego into Arizona). Roughly 25 miles east of where 94 originates near San Diego, you’ll see Highway 188. Highway 188 is only a mile long, it turns due south off 94, and it runs right into Tecate.

On the US side, Tecate is little more than the US Customs and Immigration station with a couple of buildings scattered along the road. Just keep riding south. You’ll see the signs warning you not to bring guns into Mexico (duh), and suddenly, you’ve entered Mexico. There is no Mexican border control officer. You just ride right in. You can do that going south. Don’t try it in the other direction, though.

I guess I should mention, too, that you’ll need your US passport. You can get into Mexico without showing your passport, but if you want to get back into the Estados Unidos, well, you get the idea.

The place to get your Mexican tourist visa is a bit complicated to get to. Well, sort of. It’s right there as you enter Mexico, the first building on the right, once you’ve crossed the border. You’ll bounce over a couple rows of Bots Dots (those annoying grapefruit-sized metal domes). The drill is to park (but there’s no place to park), walk across the road you just rode in on, hoof it back to the Mexican customs building (but there’s no sign on it), walk around the road through a gate as if you were walking out of Mexico, cross back again, and, if you’re like me, wonder what you’re supposed to do next. Look for the steps, go up a half a flight, and then enter the Mexican immigration area. There are no signs. Just wander around looking like you’re lost (you won’t have to act, because you will be), and ultimately, somebody will ask if you need help. I get the feeling not too many people actually get a visa when they enter Mexico. But you’re supposed to. There. I’ve said what I’m supposed to.

When you get back on your bike (or in your car), continue south on the street you came in on, and you’ll immediately see the sign telling you yep, you’re here…

A better view of the sign welcoming you to Tecate. Note the sign below…the wine country is straight ahead. Baja wines are quite good. We’re pointed due south in this photo.

Tecate is laid out kind of like a T, with the top of the T following the border to the east and the west, and the long part of the T heading south toward the Ruta del Vino wine country. The drill here is to go a block or so past the Tecate welcoming banner you see in the photos above until you T into Avenida Revolución, and then turn right. If you go about a mile or so, you’ll see one of the two places I stay when I’m Tecate. It’s the Hotel El Dorado. It’s okay and it’s not expensive. My preferred place to stay, though, is the Hotel Hacienda, which is another mile east on the same Avenida Revolución. The Hacienda has that amazing Malinalli Sabores Autóctonos restaurant I wrote about in the ExNotes blog yesterday in a connected building. The Hacienda also has more secure parking (they lock up the parking lot at night). I think the rooms at the Hacienda are a wee bit nicer, too. The price at both places is about the same, and they are both on the right side of the road as you continue west.

Hey, one thing I ought to mention is that Mexico has stop signs that look exactly like ours, but somehow they are way harder to see. If you’re approaching an intersection, start looking for a stop sign. They won’t jump out at you.

You’ll see plenty of gas stations, and in Tecate the gas stations take credit cards (that’s not always the case further into Baja). Until recently, Pemex was the only gas you could buy in Mexico. Being a government company, though, Pemex ran out of money for exploration (and then they started to run out of gas), so the Mexican government now allows other oil companies. We saw BP, Chevron, and ARCO stations in Tecate.

Tecate is dominated by the Tecate Brewery, which is the tallest thing in town. The brewery is smack dab in the center of town, and you literally can see it from just about anywhere. They used to offer brewery tours, but alas, I was unable to book one. Maybe they still do, but neither the phone number nor the email address on the Tecate website worked for me. I wandered onto the Tecate factory grounds to try to get a tour, but I struck out. A worker told me the Tecate Beer Garden is still open, but there were no tours. He said the Beer Garden was well hidden between two iron-grated doors. He was right. We couldn’t find it.

The Tecate brewery dominates the Tecate skyline. You can see the plant from anywhere in town.

Mexico’s post office uses motorcycles for delivery. The bikes we saw were CG clones offered by Italika. It looks like a cool job.

So, imagine you’ve just crossed the border into Mexico and you are at the apex of that T described earlier (the T that is Tecate). If you turn right and head west on Mexico Highway 2, you’ll eventually run into Tijuana (although why anyone would ever want to do that is beyond me). If you turn left and head east on Mexico Highway 2, you’ll eventually run into the Rumarosa Grade (a very scenic place described earlier in our blogs about the Janus trip) and then Mexicali. If you go straight and head south on Mexico Highway 3, you’ll leave Tecate and dive deeper into Baja. Highway 3 becomes the Ruta del Vino and it is a fabulous ride through the northern Baja wine country. Highway 3 ultimately intersects Mexico Highway 1 (Baja’s Transpeninsular Highway) and the Pacific Ocean at the northern edge of Ensenada.

We’ll pick up with the Ruta del Vino in tomorrow’s blog, so stay tuned!

The Ruta del Vino…a fabulous ride through northern Baja from Tecate to Ensenada.

Automatic email notifications down

Folks, it seems that the WordPress people improved the automatic email update feature. In fact, they improved it to the point it no longer works. That’s why you haven’t received an automatic email update for the last two blogs we posted.

It is frustrating dealing with (and depending on) these software weenies. We checked the WP help boards and the problem seems to be universal…the boards are inundated with comments from upset blogmeisters. Things are hopping in Mumbai, we suppose; that’s where the automatic email blog update software design is done. They are probably working the problem now.

Our apologies. Bear with us, and hopefully the wizards will sort this one out soon.
